煤巷锚杆支护结构可靠性分析

he application engineering structure reliable theory, establishes the coal lane anchor rod supports and protections built-in reliability model, in view of its structural stability limiting condition function function highly misalignment characteristic, uses the Monte Carlo method to produce directly under the Matlab environment obeys each corresponding probability distribution function the random variable array to calculate its structure reliability, the programming process simplifies, the computation speed is quick, the precision is high, and the limiting condition equation misalignment, the random variable nonnormal limit, was not opened the coal lane anchor rod supports and protections structure reliability computation new way. Has established the supports and protections parameter and reliability relations, had pointed out enhances the coal lane anchor rod supports and protections structure reliability the method and the measure, and raises for the coal lane anchor rod supports and protections parameter design to help superiorly
